Ariana Grande And Big Sean Look 'Happy In Love' During Surprise Show

Ariana Grande surprised fans at Kiss FM's Jingle Ball on Friday night, when the Grammy-nominated singer brought out her boyfriend Big Sean for a special performance.

According to Access Hollywood, Ariana brought Big Sean on stage following her own solo performance that included a guest spot by Jessie J.

"The duo looked happy in love, sporting matching red outfits and serving up some sexy PDA as they performed their hit "Best Mistake" for the crowd at Los Angeles' Staples Center," the article stated.

And while the performance went off without a hitch, Grande told Access Hollywood that she finds it hard to concentrate when performing with her boyfriend, as she gets giddy.

"I'm so nervous I'm going to laugh... But it's going to be fun. Whatever happens, happens," the "Problem" singer told Access' Shaun Robinson, of dueting with Big Sean. "It's just sort of inevitable. Silliness, I guess."

Big Sean, whose real name is Sean Anderson, and Ariana Grande first got together when Anderson contributed to Grande's second album My Everything, collaborating on the smash hit "Problem." Since then, the couple have been quite open about their relationship in public, posting photos of their romance on social media sites like Instagram and Twitter, as reported by the Inquisitr. The pair then performed together during A Very Grammy Christmas special that aired recently.

All of this has culminated in a banner year for Ariana Grande. Her aforementioned album, My Everything, has been nominated for a Grammy for Best Pop Vocal Album, while "Problem" went on to become one of the biggest singles of all time. Then there's her relationship with Big Sean that has been described as "transformative" by the singer herself. Even the surprise show was merely a showcase for more extended PDA, as E! Online is reporting.

"As Big Sean grabs his girlfriend's waist (or dare we say butt), he leans in for a kiss. But Grande innocently turns her head the other way. Aww, young love."

But not everything has gone smooth for Ariana Grande thus far in her young career. There are constant rumors that Ariana has developed a diva reputation, with recurring rumors of aggressive behavior towards both fans and event organizers. There was even a mishap at the latest Victoria Secret Fashion show as reported by the Inquisitr.

But all of that can be considered a minor distraction for Ariana, as she heads into the new year both at the top of the charts and in love with Big Sean.
